Success stories with German beverage leaders

Vilsa Brunnen is a mineral well company based in the south of Bremen with a turnover of 103 Mio USD.
In 2012, LOEHRKE had to carry out a complete hygienic retrofit for a production line for Vilsa using products with low chemical impact; He recommended the use of Claranor pulsed light for the decontamination of caps.

To preserve the premium quality of their sensitive products during all the shelf-life, Vilsa sterilizes their closures.
Until the end of 2012, the caps decontamination treatment was done with PES. Running costs were high, maintenance expensive and limited freedom in the choice of the closure due to the use of lubricant made necessary because of the use of caps with firm sealing. Vilsa Brunnen was looking for a new sterilization process. LOEHRKE presented the Claranor Cap sterilization equipment.

Since then it’s 5 filling lines that have been equipped with the Pulsed light treatment.

Main advantages highlighted by Vilsa:

  • Efficiency: >4.3 log red of the A. brasiliensis, Fraunhofer Institut
  • No sensory impact on the product compared to Peracetic acid baths process
  • Yearly costs much lower than peracetic acid baths

Located in the heart of the Alps in Austria, Wildalp is an entirely natural brand of untreated water. Its premium quality is based on the purity of its source. In order to preserve the purity of the water, the water is bottled directly at the source, allowing it to conserve its origin, its natural energy and its unique characteristics developed during its long journey in the Alps.

In 2014, Wildalpen launched a range of drinks dedicated to children based on natural spring water and worked on a new dedicated closure with Aptar. Chemical sterilization of the closure was unthinkable given the natural environment and the particularly sensitive target: young children.

As Stefan C. Hacker, Managing Director of Wildalpen Wasserverwertyngs Gmbh explains,

“Claranor pulsed light helped us create the product with these sport caps. The sterilization of the cap by pulsed light guarantees a high level of product safety and avoids sensory impacts on the product itself. The process is clean, and the reduced annual costs are a real advantage. We are fully satisfied with our solution.”

More recently, LOEHRKE built collaboration with major German dairy manufacturers

The last one, in 2020, a big worldwide player of the dairy market integrated a Claranor Cup decontamination equipment on a 9 strokes cup filling line to protect their innovative premium dairy alternative dessert.

This unit installed in Germany is the 9th ordered by this customer and always to address the mould issue faced with their sensitive products. For their premium product :

  • chemical is not an option to prevent any risk of chemical residue
  • and UV middle pressure process are not either.
  • UV MP proved after long tests run that they were not efficient at all to protect the product from mould issue.
